dollars is approximately equal to 8.72 Euros.
Which equation shows the approximate value, in Euros, as a function of U. S. dollars on this day?
y=0.873 +0.02
y=0.877 +3.50
y=3.50.1 +0.02
y=3.503 +0.87

step-by-step explanation:

$119.20

step-by-step explanation:

$372.50 - 60% off is $149. $149-20% off is $119.20

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
